Advocate is a monthly spot-on treatment for dogs weighing 4–10kg, covering fleas, heartworm, intestinal worms, and ear mites in a single application. It's a prescription-class topical that vets commonly recommend as a broad-spectrum monthly preventative.

The active ingredients — imidacloprid and moxidectin — address both external and internal parasites. Imidacloprid acts on adult fleas and larvae in the environment; moxidectin covers heartworm prevention and gastrointestinal nematodes including roundworm, hookworm, and whipworm. Ear mites are also covered. The spot-on format applies at the back of the neck, where dogs can't lick it off.

Advocate suits owners who want a single monthly treatment that doesn't leave gaps in parasite coverage. It's a common choice for dogs in tick-prevalent areas where a product handling multiple parasite classes simplifies the treatment calendar.
